RAIL-ANCHOR.

Specification of Letters Patent.

Original application filed December 15, 1913, Serial No. 806,773. Divided and this application filed October 5, 1914. Serial No. 865,087.

To all whom. it may concern:

Be it known that I, PHILIP W. MOORE,"L citizen of the United States, residing at Evanston, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Rail-Anchors, of which the following is'a specification.

invention relates to the class of devices known as rail anchors, rail stays, or anti-creepers, the purpose of which is to provide an engagement between railroad rails and the ties on which they are laid (or other stationary, or relatively stationary,-

elements of the road-bed) which checks the well known tendency of rails, under certain conditions, to creep in'the direction of their length; and the object of the invention is to provide a simple, inexpensive device of this type which will be strong, light in weight and so constructed that the tendency of the rail to which it isapplied to move longitudinally is self checking.

The invention contemplates particularly the type of rail anchor utilizing wedge action between relatively movable parts of the.

yoke or shoewhich extends under the base of the rail and engages thesame at opposide edges, said yoke being made preferably, though not necessarily, of a single integral structure which may be either rigid or slightly flexible as desired, the other consisting of a wedge element interposed between the yoke and the rail which wedge element is subjected to lateral stresses tending to de-' form or strain the same in directions transversely of the railwhen the forward thrust of the rail moves, or tends to move the free element of the anchor toward. the tie against which the other element is abutted.

The inventionhas for further objects such other new and improved constructions, ar-

' vation.

ra'ngements and devices relating to rail anchors as will be hereinafter described and claimed. 4

This application is a division of my copending application Serial No. 806,773, filed December 15, 1913;

- The invention is illustrated, in a preferred embodiment, in the accompanying drawings Figure 1 shows a rail anchor, constructed in accordance with the invention, applied to a rail, the rail being shown in section and the tie against which the device is abutted in ele- Fig. 2 is a plan view of therail anchor, rail and tie shown in Fig. 1 Fig. 3, a. sectional elevation taken on line 33 of Fig.

2,;Fig. 4, a vertical sectional view, with the rallshown in elevation, taken on line 4-4 of Fig. 1; Fig. 5, a view, in-perspective, of the wedge element, and Fig. 6', a similar view of the yoke element.

Like characters of reference designate like parts in the several figures of the drawings.

Referring to the drawings, Adesignates a railroadrail to which the device is applied, and B one of the cross ties on which the rail is laid. The anchor consists of a yoke member C (Fig. 6) and a hollow wedge member D. The yoke member C is made up of'a bar 'of metal, the ends of which are bent over so as to form hooks" 10-- which bear against the oppositeedgesof'the rail base 11.

from the tie than at the opposite edge. 13 and is bent at the middle as shown, at 14, or is otherwise formed-so that when the yoke is in position on the rail two wedge faces 15, 15 are provided which have a downward slope in the direction toward the tie and inwardly toward the center axial line of the rail base.

The wedge member D consists of a tie abutting member 16, a pair of wedge members 17, and a connecting web 18, the members l7 diverging from the connecting web toward the tie abutting member.

wedge members 17 are formed with preferably rounded wedgesurfaces 19 which have The an inclination corresponding generally to the inclination of the surfaces 15 on the yoke.

The anchor is applied to the rail by placing the wedge element; under the base'fi'ange.

of the rail with its tie abutting member 16 The bar is'thick'er at the edge 12 remote bearing against the tie, placing the yoke on the base flange of the rail back of the wedge element, and driving it toward the tie as far as it will go. Vhen the parts of the anchor have been brought in this manner into intimate contact with each other and with the rail, the forward thrust imparted by the wheels of the train to the rail will be transmitted to the free element or yoke C of the anchor, and thence to the wedge members 17 of the hollow structure D. The stresses exerted against the' hollow member D would, if not resisted, tend to force the wedge members 17 inwardly toward each other. As the hollow structure D is made capable of withstanding these stresses without being broken or suffering any considerable strain, a wedging action is produced between the parts of the anchor and between the anchor and the rail base which checks the forward thrust of the rail. The hollow configuration of the wedge member necessarily gives it a certain elasticity laterally whereby the hold between the elements is made more intimate and vibration is absorbed, minimizing the tendency of the parts to work loose.

While I have shown and described my invention as embodied in a preferred construction, modifications in the form and proportion of theparts might be made without departure from the principles of the invention.

I claim: 5

'1. In a rail anchor, the combination with I the rail both transversely and longitudinally a bar formed at opposite ends with hooks adapted to bear against the upper surfaces ofthe base flange of the rail, of a tie abutting plate, and separate wedge 7 members formed on said plate with an open space intervening between them, which extend under opposite edges of the base flange of the rail and intervene between said bar and the bottom of the rail directly under said hooks.

2; In a rail anchor, the combination with a bar formed at opposite ends with hooks adapted to bear against the upper surfaces of the base 'fiange of the rail, of a tie abutting plate, and wedge members formed, on saidplate'adapted to intervene between said bar and the bottom of the rail directly under said hooks, said bar and wedge members being-formed with coactingsurfaces having an inclination with respect to the plane. of the rail basedocth longitudinally and transversely thereof. 13. A rail anchor comprising two relatively movable elements, one adapted to extend around the base flange of the rail and provided with overlapping parts adapted to bear against the upper surfaces of thebase flange on opposite sides of the rail, the other providing wedges which extendunder opposite edges of the base flange of-the rail directly under the overlapping parts of the,

first named element, said wedges and the element with which they are engaged being pair of wedges which extend under opposite edges of the bottom of the rail directly under the overlapping parts of the first named element, said wedges and the element with which they are engaged being formed with coengaging surfaces which are oblique to the plane of the bottom of the base flange both longitudinally and transversely of the rail.
